Messagepump freezes

[Bekjong]

Hello, I have a big project here (all in .net 2.0 and c#) that seems to experience message pump freezes on some computers. At least thats what I'm thinking: This specifically seems to happen when scrolling the mousewheel within a DomainUpDown control and then leaving it's bounds with the mousepointer, while still scrolling the mousewheel. The application just freezes completely (including all background threads). Right-clicking the application in the taskbar seems to restart the pump. I've tried overriding the OnMouseLeave method of the control and then calling System.Windows.Forms.Application.DoEvents() from there, but that doesn't seem to help. (And yes, I know it isn't very good practice to be calling that method in the first place ;)). Any help is very much appreciated, thank you in advance!

Standards are great! Everybody should have one!
